Abstract
Different chemical compounds have been studied to optimize dosimetric systems in irradiation processes. In this study the behavior of the potassium nitrate in pellet form was investigated in a 60Co gamma field, in order to verify if it can be used as a dosimeter. Fricke solution was used as reference dosimeter to determine absorbed dose rates of the gamma facilities. The potassium nitrate (KNO 3) solution response is radiation sensitive and reproducible for absorbed doses from 1 to 150 kGy. The detection technique used was spectrophotometry in the visible region, which allows relating optical absorption, before and after irradiation. The potassium nitrate prepared in pellet form was dissolved in pure water for optical measurement. The maximum absorption wavelength was observed at 546 nm. Calibration curves were obtained and are linear in all dose interval studied. All the evaluations are presented in this work.
